Don't use a debit card for the rewards -- It'll cost you more than you make!
Hoping to augment the natural shift toward debt cards, some banks are offering rewards to people who buy stuff with debit cards -- a perk that was once only available to credit card users. USA Today reports that "Integra, a Midwestern bank, introduced its first debit card reward program in July. Sovereign launched a debit rewards program late last year. And credit unions such as Addison Avenue Federal - whose customers are employees of high-tech companies - are offering new perks if consumers use debit cards a certain number of times a month."
